BROODER STOVE Filed April 28, 1930 2 sheeis-sheet 2 Patented May 10, 1932 JOHN HENDERSON, or oAnILnAc; IcHIGnN BROODER *STOVE Application filed April 23,

This invention relates to stoves, and more particularly stoves especially designed for use in connection with brooders, chlcken coops and the like, the primary object of the invention being to provide a stove of the hanging type so that an even and uniform temperature will be insured throughout the entire area of the brooder or chicken house in which the stove is used.

1o Another object of the invention is to improve generally the construction of the stove as shown and described in my Patent No. 1,189,691, by providing thermostatically controlleddraft regulating means so that the efiiciency of the stove will be increased and a predetermined temperature insured at all times.

With the foregoing and other objects'in view, which will appear as the description =3.) proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention 2:, herein disclosed, may be1m'a'de within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings: Figure 1 is an. elevational View of a stove I so constructed in accordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is a transverse sectional view through the stove.

Figure 4 is a fragmental vertical sectional :15 View through the stove.

Figure 5 is an enlarged fragmental sectional view through the shell of the stove. Figure 6 is a fragmental detail view of the thermostat supporting arm. Figure 7 is an enlarged fragmental sectional view showing the air nozzles and caps 'mi't of the groove formed therein providing a race for the balls 10 that engage the p'pe l1, asclear ly shown by Figuret'of the drawings.

I j The lower end "of the pipe 11' is fianged at" l 12 to provide a support for the shell and body 7:55

portion. Thus it will be seen that due to t-his construction, the body portion may be rotated with respect to the pipe 11 tothe end that-the operator may attend the stove without. the necessity of walking around the stove. Positioned'within the stoveis a cylindrical drum 130f smaller diameter than the shell or casing, to provide an annular spacebetween the drum and casing providing a com? bustion chamber in which, the grate'lzgis located." V q The reference character 14 designates the hinged bottom of the stove, sna s shown; air nozzles 15 extendinwardly fromthe shell, at f points directly above thebottom l lj fThese r I nozzles are ;in communication with the "atmosphere, the same having their outer ends supported Within openings of the-shell. x

Secured to theouter surfa'ce of the shell,'are a brackets 16 formed'with'extensions 17 provid ing' guides for the band 18 whichjisislidably mounted'w'ithin the guides, there being providedpins *19, extending through the ex'ten v sions 17 to hold-the band in position, but pery y necessary sliding movement of; the 86 hand. L l f .iCajrried by -th'e band are closures 20 at? ranged adjacentto the outer ends of the n'ozzles '15,;so'that by moving the closuresj'20 i over the outer ends ofthe nozzlesgthe-ldraft B5 throughthe nozzlesmay be-regu'latedl 1 This band-18 is thermostatically controlled,

the thermostat being indicated by therefer ence character 21', the same being in-the form f of expansible 'di sks. [This thermostat is secured to the laterallyjextended portion-22 of the arml23, which has its upper end boltedto the-wheel of body portioin'by 'means'of the bo1t24l l An-elongated opening isformed in thearm 9-5 V,

23 and accommodatesjthe bolt25 which'also extends-through an opening in the arm 26 that' is provided withalaterallyextendedpor I v tio'n227 overlying :the-porti0n22of the arm 23." 'l lie'thermostat is also connected with 9 extends laterally from the band 18, causing I la rotary movement of the band, upon vertical movement of the arm 26.. VA coiled spring g has connection with the bell crank lever 28, the coiled, spring having its lower end anchored to the laterally extended portion 22, with the result that the spring will tend to return the bell crank lever to its initial position,

as the thermostat returns to its normal position. v I

The hood which is indicated by the reference character 31 is designed to fit over the body portion of the stove, the hood being supported by the cables 32 that pass over the pulleys 33 mounted onthe supporting plate 34. The operation and construction of the hood 31 is clearly set forth in my Patent No. 1,189,691.

Thus itwillbe obvious that due to the construction shownand described, the draft to the stove will be regulated automatically, and an even temperature within the stove will beiinsured at all times. 1

, I claim: a V

V 1. A device of the class described, a body portion having a combustion chamber and having openings establishing communication between the combustion chamber and atmosphere, brackets secured to the outer surface of the body'portion, upper and lower extensions forming a part of the brackets, a band surrounding the body portion and operating between the extensionsv of the brackets to guide the band in its movements, closures carried by the band and adapted to move over the openings to regulate the passage of air through the openings, and thermostatically controlled means for operating'the band.

2. In a device of the'class described, a body portion having a combustion chamber and having openings establishing communication between the combustion chamber and atmosphere, a band surrounding the body portion andmovable in a horizontal plane, closures carried by the band and adapted to move over the openings toregulate the passage of air through the openings, an arm extending downwardly from the body portion, said arm having a right angled end portion, a bell crank lever supported between the ends of JOHN HENDERSON.
